Description

[01] Field of technology

[02] The utility model relates to the field of construction, namely to the fastening points of easily dropped elements of enclosing structures and can be used for fastening shifting or pivoting window elements that are released under excessive pressure resulting from an explosion.

[03] State of the art

[04] The closest analogue of the utility model is the fastening unit of the easily dropped element (leaf) of the building envelope, described in the patent of the Russian Federation RU 2731966, 09.09.2020. Said attachment assembly includes a bracket in the form of a plate having holes for attachment to the L-shaped profile of the supporting element (frame) and the T-shaped profile of the easily dropped element (leaf), the mounting planes of which are placed in parallel. The assembly also contains an embedded element in the form of a plate placed inside the profile of the easily dropped element. Also, the design provides for a destructible connection containing a destructible washer and a screw passing through the destructible washer, the bracket hole and further into the profile of the supporting element and the embedded plate of the profile of the easily dropped element.

[05] The main disadvantage of the analog is the complexity of maintenance of the easily resettable structure. When the embedded plate is located inside the profile of the easily dropped element, there is no possibility of its rigid fastening. When replacing a destructible element, in this case, the risk of displacement of the embedded plate increases. Incorrect fixation of the safety locking device will result in failure of the device. To correct the structure, it will be necessary to completely disassemble the structure, which is difficult to do on a window block already fixed in the opening.

[06] Disclosure of the utility model

[07] The main technical problem, which is aimed at solving the claimed utility model, is the complexity of maintenance of the easy-to-reset structure.

[08] The technical result of the utility model is to simplify the maintenance of the mount associated with the replacement of elements.

[09] This problem is solved, and the technical result is achieved in the utility model due to the fact that the fastening unit of the easy-to-reset element of the enclosing structure includes: the element and the profile of the easily dropped element are parallel to the planes; a fastening plate adapted to be attached to the profile of the easy-to-reset element and having a hole; and a breakable joint comprising a breakable washer and a threaded fastener. In this case, the mounting plate is made with the possibility of fastening outside the profile of the easy-to-reset element, the fastening unit additionally includes a distance sleeve located between the mounting plate and the bracket, and the threaded fastener of the destructible connection passes successively through the destructible washer, the hole of the bracket for fastening to the profile of the easy-to-reset element, the hole distance sleeve and mounting plate hole, and also has the ability to pass into the profile of an easily dropped element.

[010] In addition, according to particular embodiments of the utility model:

[011] The bracket is made in the form of a plate, the first part of which is made with the possibility of adhering to the profile of the carrier element, and the second part - with the possibility of protruding relative to the profile of the carrier element, wherein the hole for attaching to the profile of the carrier element of the bracket is made in its first part, and the hole for fastening to the profile of an easily dropped element - in its second part;

[012] the destructible connection includes a distance washer placed with a gap in the hole of the bracket for fastening to the profile of the easily dropped element;

[013] The threaded fastener of a breakable connection is a screw,

[014] An easy-to-reset element is a pivoting or movable window element or wall panel.

[015] Unlike the closest analogue, the fastening plate is not an embedded element and is located on the outer part of the profile of the easily dropped element, and a distance sleeve is additionally placed between the fastening plate and the bracket, which makes it possible to displace the screw of the breakable connection so that it does not pass through the profile bearing element. Such external fastening of the elements of the fastening unit allows, without additional difficulties, to replace the destructible element during the maintenance of the structure.

[016] In addition, the design of the mount provides:

[017] increasing the reliability of operation through the use of a distance sleeve that eliminates the deflection of the bracket,

[018] increase in versatility due to the possibility of installation in any opening, including in the presence of quarters,

[019] maintaining the integrity of the profile due to the fact that embedded parts are not placed inside it,

[020] maintaining the tightness of the structure due to the fastening of the elements on the outer part of the profile of the supporting element, which does not violate the contours of the seal.

[026] Implementation of the utility model

[027] The easy-to-reset structure using the claimed utility model is formed by the L-shaped profile of the supporting (fixed) element (1), in particular the window frame, and the T-shaped profile of the easy-to-reset element (2). The easy-drop element can be a window element in the form of a pivoting sash, which opens outward by rotation around the axis of the hinges when exposed to excess pressure or a displaceable element that falls out when exposed to excess pressure). Also, a wall panel, such as a sandwich panel, can be used as an easily dropped element. Mounting surfaces of profiles (1) and (2) are placed in parallel planes. The specified profiles (1) and (2) are connected by means of the claimed attachment point, which is a structurally single device, including a bracket (3) adjacent to the mounting surface of the profile of the bearing element (1), a mounting plate (4) adjacent to the mounting surface of the profile easy-to-reset element (2), spacer bushing (5) located between bracket (3) and plate (4), as well as destructible joint (6) that fastens bracket (3), bushing (5) and plate (4) to each other.

[028] The bracket (3) is made in the form of a plate, one part of which is adjacent to the mounting surface of the profile of the carrier element (1), and the second part protrudes relative to this surface. At the same time, at least one hole (7) is made in the first part of the bracket (3) for fastening to the profile of the supporting element (1) using a threaded element (self-tapping screw) (8), and in the second part - a hole (9) for fastening to the profile of the easy drop element (2).

[029] The mounting plate (4) is rigidly attached to the profile of the easy-drop element (2), for example, by means of threaded elements. In this case, the plate (4) includes a threaded hole (10) for a destructible connection (6).

[030] Destructible connection (6) is formed by a destructible washer (11) placed on the outside of the bracket (3) and a threaded element (12), for example, a screw. To improve the reliability of operation, the breakable connection (6) may additionally include a spacer (13) placed in the hole (9) of the bracket (3) with a gap. In this case, the threaded element (12) of the breakable connection (6) passes successively through the breakable washer (11), the spacer (13) in the hole (9), the hole of the spacer sleeve (5), the threaded hole (10) of the mounting plate (4) and enters into the profile of the easily dropped element (2).

[031] Destructible washer (11) may be made of a polymeric material, such as polymethyl methacrylate. In this case, the material and geometric dimensions of the washer (11) are selected on the basis of ensuring the possibility of destruction of the washer when excessive pressure occurs inside the room, as well as maintaining the integrity of the washer when exposed to normal operating loads.

[032] The mount works as follows.

[033] The profile of the easily dropped element (2) under the influence of the explosion load inside the room is displaced or opens (for the sash) outward relative to the profile of the supporting element (1) of the building together with the plate (4), the sleeve (5) and the threaded element (12). The head of the element (12) pushes the breakable washer (11) through the hole (9) of the bracket (3) and breaks it. Continuing the movement, the threaded element (12) together with the distance washer (13) passes through the hole (9) in the bracket (3) and together with the sleeve (5) and the plate (4) are disconnected from the bracket (3), freeing the discharge opening. The bracket (3) remains attached to the profile of the bearing element (1) with threaded elements (8). During the destruction of the washer (11), the distance washer (13) prevents the head of the element (12) from engaging over the edge of the hole (9). At the same time, the presence of a gap between the distance washer (13) and the inner wall of the hole (9) contributes to an easier separation of the elements.
